I saw an old single shot 20 gage in a pawn shop. It was made by Springfield Arms in Chicopee. I'd heard these are actually Savages. No blueing left, but the bore looked great.

The only number that looked like a serial was inside the receiver where the breech of the barrel sits. At least that is what the shop owner said was the serial. That number was mid 5000's. Any way to find out how old is? Thanks.
